Functional Verification

The Functional Verification Test for the E1364A switch consists of sending the *IDN? command and checking the response. This test can be used at any time to verify that the switch is connected properly and is responding to basic commands.

Procedure 1. Verify that the switch is installed in the mainframe and that the mainframe has passed its power-on test.

2.Send the *IDN? command to the switch module (see example following).

3.The switch module should return the following string (revision number may vary):

HEWLETT-PACKARD,SWITCHBOX,0,A.06.00

NOTE If the primary address setting, secondary address setting, or interface select code is set incorrectly, the switch will not respond. Verify proper address selection before troubleshooting.

Example An example follows which uses an HP 9000 Series 300 computer with HP BASIC and a switch address of 70915.

10	DIM A$[80]
20	OUTPUT 70915;"*IDN?"	!Send the ID command
30	ENTER 70915;A$	!Get response

Operation Verification

The procedures in this section are used to provide a high confidence that the switch module is meeting published specifications. The Operation Verification tests are a subset of the Performance Verification tests and are suitable for checkout after performing repairs.

Operation Verification is performed by completing the Closed-Channel Resistance Test as described in the Performance Verification test procedures. This test is usually sufficient to verify that the switch module is meeting its specifications.
